In this letter, field dependence of the low-temperature dielectric permittivity and polarization of Mg-doped SrTiO3 films is studied. Incorporation of Mg on both Sr and Ti sites decreases the \u03b5\u2032 and relative tunability nr of sol-gel derived SrTiO3 films, whereas polarization is reduced by Ti site substitution only. tan\u2009\u03b4 of the studied films is \u22640.012, decreasing at low temperatures down to 0.001 when Ti is substituted by 5% of Mg.<\/jats:p>","DOI":"10.1063\/1.3360213","type":"journal-article","created":{"date-parts":[[2010,4,13]],"date-time":"2010-04-13T22:33:05Z","timestamp":1271197985000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":7,"title":["Low temperature dielectric characterization of Mg-doped SrTiO3 thin films prepared by sol-gel"],"prefix":"10.1063","volume":"96","author":[{"given":"Olena","family":"Okhay","sequence":"first","affiliation":[{"name":"University of Aveiro Department of Ceramics and Glass Engineering, CICECO, , 3810-193 Aveiro, Portugal"}]},{"given":"Aiying","family":"Wu","sequence":"additional","affiliation":[{"name":"University of Aveiro Department of Ceramics and Glass Engineering, CICECO, , 3810-193 Aveiro, Portugal"}]},{"given":"Paula M.","family":"Vilarinho","sequence":"additional","affiliation":[{"name":"University of Aveiro Department of Ceramics and Glass Engineering, CICECO, , 3810-193 Aveiro, Portugal"}]},{"given":"Alexander","family":"Tkach","sequence":"additional","affiliation":[{"name":"University of Aveiro Department of Ceramics and Glass Engineering, CICECO, , 3810-193 Aveiro, Portugal"}]}],"member":"317","published-online":{"date-parts":[[2010,4,13]]},"reference":[{"key":"2023070223261631400_c1","doi-asserted-by":"publisher","first-page":"2117","DOI":"10.1109\/22.963146","volume":"49","year":"2001","journal-title":"IEEE Trans.
